Quotes - Engineering - SalesFour Ways to Get Surface Into a Vessel
Which one applies is settled before any thermal calculation: whether the contents can be pumped at all, whether the vessel already exists, and what the jacket side has to be rated for. An existing tank that must not be cut into points one way; a vessel still on the drawing board points another.
- Tank jacket retrofit. A tank that needs heating it does not have usually presents two expensive options — replace it, or cut into it. A clamp-on panel is the third one.
- Immersion heating. For fluids too viscous, too abrasive or too valuable to pump out, and for batches that must not be disturbed, an immersion assembly puts the surface into the tank instead.
- Vessel and reactor cooling. Reaction heat has to leave at the rate it is produced. Jacket surface, medium temperature and control all belong to the same problem rather than to three separate ones.
- Drum and roll cooling. Chill rolls, flaker drums and drying drums need a uniform surface temperature across the working face above everything else, and that is what inflated wall construction delivers.
- Formed to the vessel. Inflated panels can be pressed to shape, welded into a component, hung inside a vessel or clamped to the outside of an existing one, which is what makes the retrofit possible at all.
- Rate the jacket, not just the duty. Design pressure and temperature on the jacket side, and whether the vessel carries a code stamp, belong in the enquiry alongside the heat load.
What Decides the Selection
Whether the contents can be pumped, whether the vessel already exists, the design pressure and temperature of the medium, and whether the surface can be inside the tank or has to stay outside it. Corrosive contents and product contact both push toward specific answers.
Why Temp-Plate Suits Tank Work
Inflated panels can be formed to shape, welded into a component, hung inside a vessel or bolted to the outside of one. They are fully welded with no gaskets, they need less circulating medium than traditional dimple jacketing, and a clamp-on retrofit never cuts the pressure boundary of a tank you already own.

Yes, with a clamp-on Temp-Plate jacket. Panels bolt to lugs welded to the outside of the shell with heat transfer mastic between, so the pressure boundary is never cut and downtime is minimal.
Inside gives better heat transfer because the surface contacts the fluid directly. Outside avoids product contact entirely and can be retrofitted. Corrosive or abrasive contents and sanitary requirements usually decide it.
A coil contacts the fluid only along the tube. Temp-Plate gives continuous surface across the panel face, needs less circulating medium and is easier to clean around. Coils still win at very high media pressure.
Substantially less than traditional dimple jacketing, because the inflated passage volume is smaller. That shows up directly in pump size and pumping cost over the life of the system.
